LPC55S69 安全启动中能以 哈希值 来指定要引导固件吗?

看文档 安全启动 是用 RSA 证书来验证引导固件的。

有其他的固件验证方法吗?

比如不考虑固件更新问题,能否强制以 SHA-256  来验证要引导的固件?

HI

LPC55Sxx devices support booting of RSA2048 signed images using RSASSA-PKCS1-v1_5 signature verification. 2048-bit or 4096-bit RSA keys are supported. Others are not supported.

Have a great day,
Jun Zhang
